Technology Development for Carbon-Ash Beneficiation by ...

Fly ash with high unburned carbon, often measured as loss-on-ignition or LOI, is not acceptable for applications such as concrete production. High LOI's in fly ashes are becoming more of a problem with the installation of low NOx burners. Therefore, an efficient and economic dry beneficiation technology that removes...
